Shahram Amiri, the Iranian nuclear scientist, has described the moment he claims to have been abducted at gunpoint by the CIA while on a pilgrimage in Saudi Arabia.
Manouchehr Mottaki, foreign minister, said the government would wait until it knew "what has happened over these past two years, and afterwards we will see if he will be considered a hero".
Mr Amiri's account leaves some questions unanswered, such as how he managed to escape from the CIA. He said he was helped by "friends", but does not say who they were or how they made contact with him.
The US government is maintaining that he came of his own free will, and that he is returning due to pressure on his wife and child.
If he freely came to the US, without getting his family out of Iran first, I think he made a serious mistake. And I don't think he will fare well back in Iran.
If his story of abduction is true, it would be a black eye for the US. But his escape from detention is a bit puzzling, especially if he was considered important enough to kidnap in a foreign country
